6: How is a rising sea level a problem for coastal communities?
Because of saltwater intrusion into the coastal aquifers
6: How is a rising sea level a problem for coastal communities?
It isn't - as long as the aquifer is healthy, there will always be enough pressure to hold back the seawater
6: How is a rising sea level a problem for coastal communities?
It is actually a positive, because there will be greater pressure in wells further inland
